TOPIC: Duct cleaning and CO detectors

Yeah I wish I could have only spent $300-400.  A year after I got my house I had to replace my H/A and the ducts.  I went from rusted out ducts in the foundation to attic ducts.  $2000   >

I paid $350.

They had a large vacuum outside.

The guy said the reason they went off is reverse pressure.

They cut a 8 inch hole at the plenum and cold air return. They drill small holes at each section of supply vents that have seperate sections. They use whip(aggitator) to loosen the dirt. The talk off the return air vents and vacuum. The use an air hose for the supply.

They plug the small holes with plastic caps. They cover the large holes with shhet metal.

The guy said when we do an inspection take the cold air return off by the nearest entrance and show the clients the dirt. (Beyond SOP)

We did notice a small layer of dirt on most areas of the home due to how dirty the ducts were. 44 years worth

They did a good job, I would recommend them.

I always recommend cleaning ducts on older houses.  Most people don't think about it or think its very low on their to do list.

Dave - from what you describe it could be that they drew air down from the water heater vent and up towards the bedrooms.  Do you have gas appliances?  I can't think of where else reverse pressure would have gotten the CO from.

I don't take off the covers, but I always show people any built-up stuff with my flashlight.  I tell them that it is more than just dust, but also accumulated organisms...  that gets them to understand.

Yes I have a gas water heater.

For 300-400 dollars a well worth investment.

Will go into my Improve section.

Need to come up with some verbage. Care to offer an example.

Here is mine.

Improve: Now acknowledged as a major allergy and disease causing problem by leading medical authorities, poor indoor air quality has prompted doctors and allergists to commonly prescribe furnace and air duct cleaning as a remedy. Duct cleaning can reduce heating and cooling costs by allowing your system to operate more efficiently. Moreover, duct cleaning can cut maintenance cost because a clean system has fewer breakdowns. Standard throw-away fiberglass filters remove less than 7% of these particles, which means much of the rest settles in your air ducts. Contact a qulaified contractor to perform the duct cleaning process.

This is long and I need to work on the comment. Any ideas are welcomed.

I think $300-400 is well worth the expense!  For so many reasons.

As to your verbiage, it is not too long.  The length emphasizes its importance.  I would say only to change one thing -- "Moreover, duct cleaning ALONG WITH REGULAR SERVICE can cut maintenance costS because a clean system has fewer break downs AND CAN LAST LONGER."  That's a super paragraph Dave.  ;D

On my reports I routinely recommend an allergy-free filter.  I have used them from day one in my house (10 years old) and every time our HVAC guy comes for my annual service he comments on how clean the systems are.
